LANTERN.

SPECIFICATION forming part of Letters Patent No. 343,461, dated June 8, 18 6.

Application filed April 8, 1886. Serial No. 198,214. (No model.)

To all whom, it may concern,.-

Be it known that I, FRANZ KUNTZ, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Lanterns, of which thefollowing is a specification.

My invention relates to improvements in lanterns; and it consists, essentially, in a lantern having a polygonal or cylindrical body, an inclined translucent front, and a retlector on its bottom to direct the rays of light upward and outward through the inclined front. In combination with the above-described elements are additional reectors on the sides and the back of the body, an air-tight inlet, a movable lamp, a chimney for the escape of the heated gases of combustion, and a suspension device, whereby I have constructed a lantern which is especially suitable to illuminate the interior of brewers vats while such vats are being varnished Without igniting the volatile gases from the varnish.

lThe peculiar construction of this lantern is more fully pointed out in the following specitcation and claims, and illust-rated in theaccompanying drawings, in which- Figure l represents a transversesection of the lantern in theplane x x, Fig. 2. Fig. 2 is a longitudinal section thereof in the plane y y, Fig. l. Fig. 3 is a sectional view showing the lantern applied to a vat so as to illuminate the interior thereof.

Similar lettersindicatc corresponding parts.

In the drawings, the letter A designates the body ofthe lantern, which is preferably of a hexagonal cross-section, but muy be made with more or less sides, or cylindrical. The front A', Fig; 2, of this polygonal body is cut obliquely to slope from the top outward, and is closed by a pane of glass, so that the rays of light may be deflected upward through thc same, while the back is closed by a door, B, that is hinged at its lower end to the body by a linlchinge, 7), so that it can be swung downward to gain access to the body of the lantern.

Gis the lamp or candle support, which is adjustable in the direction of the length of the lanternoody on ways c c, that vare soldered or otherwise secured to the latter. IVhen candles are used,the supportisprovided with the well-known spring-sockets, as shown in the drawings, to receive the same; but when a lamp is used it must be provided with ways to receive the lamp-reservoir, as usual. I

To reflect the rays radiating from the source of light upward and outward through the inclined front A, I make use of a reiector, D, of silvered glass or other suitable material, which is secured to the bottom of the body. In the example shown in the drawings the ways c cof thelamp support also serveto clamp the reflector D down to the bottom, the latter being inserted under the ways through the open back of the body. A second reflector, D', attached to the door B,serves to throw the light outward, and in order that it may also reflect the rays upward through the front I slightly incline the said reector with its lower end toward the front. This reector is secured to thedoor at its top by a clamp, d, and its bottom rests on a socketed bracket, d. Additional reflectors, D2 D3, are attached to the sides 2 and 3, Fig. l, which are held in place by clamps d2 d?, that are soldered to the body,

and also by the ways c c.

To furnish the lantern with the necessary air, an air-inlet tube, E, is secured to the cover, and this tube is closed by a damper, E, that slides in ways e c, Fig. 2, formed on said tube, so that by adjusting this damper the supply of air to the body can be regulated.

To prevent the lamp from being extinguished in case the damper In should be accidentally adjusted so as to completely shut off the sup plyT of air, I provide one or more small holes or auxiliary inlet-orifices, c', in the bottom of the lantern-body. A chimney, G, leads from the top of the body A, through which the products of combustion make their exit. An eyel or other 'suspension device, I, is secured to the top of the lantern-body' in front of the chimney, which eye is also convenient as a handle when carrying the lantern.

The brewers vats in ordinary use frequently require a new coat of varnish on the interior, and when ordinary lanterns are used to illuminate the interior of the vat the volatile gases from the varnish are liable to come vin contact with the flame and explode. To prevent this I have constructed my improved 1antern, to the interior of which air can have -access only through the proper air-1nlet orifices.

IOO

In applying my lantern to avat, Fig. 4, it is inserted through the 1nan-hole just suiiiciently to bring the top edge of the front beyond or on line with the inner l'ace of the staves, and is held by a nail or other retaining device secured to the vat. The chimney can be carried upward and away from the vat.

It will be observed that the lantern will brightly illuminate the interior of the vat, since the light is reflected upward through the obliquefront of the lantern, and that the air supplied to the Haine is drawn from outside of the vat, and consequently there can be no danger of an explosion. i

What I claim as new, and desire to secure by Letters Patent, is

l. A lantern having a polygonal or cylin drical body, an inclined translucent front, and a reflecting-surface on its bottom to direct the rays upward and outward through the ineli ned front, substantially as shown and described.

2. A lantern having a polygonal body, an

inclined translucent front, abottoni redectingsurface, a rellectingsurface ou its sides forming an angle with the bottom reflecting-sun face, and a reflecting-surface on its back, substantially as shown and described.

3. The combination, with the body A and the eye or handlethereoi, of the inclined trans* lucent front A', the reflecting-surface D. arranged on its bottom, the reflectors D I)2 on the sides, the adjustable lamp-support C, the hinged door B, the inclined reflector D', secured thereto, the ainsupply tube E, the adjustable damper E thereof', and the chimney (I, substantially as set forth.

In testimony whereof I have hereunto Set my hand and seal in the presence of two subseri bi ng witnesses.
